One word: Magic! Who doesn't love a book with lots of magic -  readers will find mystery, wisdom and courage inside the pages.

Fox follows up The Charmed Children of Rookskill Castle with this title that stands alone, but would mean more if the aforementioned is read first.

Isaac is gifted a necklace and mysterious box by his father, before the family flees the Nazis. When Isaac has to travel on without his parents, he is set on a quest to find out the importance of the items, and what his purpose is. His destination is Rookskill Castle, where he finds four other kids about his age that all seem to have some level of magical ability that they are using to help the allied forces in the war. With Isaac's arrival magic in and near the castle seems to be going a bit haywire.

Will Isaac find his place in the magical world, if he is in fact magical? What purpose do the items left by his father serve, and is Isaac ready for all that lies ahead?

An odd mix of WWII, good vs. evil, magic, fae, wraiths, dragons, and time travel. This book has bits of fantasy to meet all of this genre's interests.

Isaac lives in Prague in 1942 He’s Jewish, and people around them are starting to disappear, like his teacher. One night, Isaac’s parents send him away after giving him mysterious objects; an eternity knot necklace and a casket that he is told not to open until he gets to Rookskill Castle. However, something is hunting them and him. 

Isaac escapes with people who help smuggle him to Scotland, and once he arrives, he is transported through time to meet with his parents, who give him some cryptic clues he needs to solve. Unfortunately, his parents are not able to stay with him, as the being that hunts them arrives. Isaac makes his way to Rookskill Castle, not without incident, and he meets the other children and magical beings there. As he attempts to solve the clues and avoid what is hunting him, Isaac makes friends and learns about his own power. 

Although some mentions are jarring to those who may know more about the legends (e.g. King Arthur in the 1300s), the overall premise of this book is intriguing. I am not sure about the author’s depiction of an Andean civilization in 1000 AD and would be curious to see the research that the author had done to ensure the representation was as accurate as possible. The research was not included in the eARC that I read.

I received an eARC from Netgalley in exchange for an honest review.
